Specification of Letters Patent.

Patent-ed May 5, 1914.

Application filed July 2, 19-10. Serial No. 570,133.

To all whom it may concern:

Be it known that I, FRANK J. DUX, a citizen of the United States,residing at Utica, in the county of Oneida and State of New York, haveinvented certain new and useful Improvements in Refrigerators, of whichthe following is a specification, reference being had therein to theaccompanying drawing.

My invention relates to an improved refrigerator and I declare thefollowing to be a full, clear, concise and eXact description thereofsufficient to enable anyone skilled in the art to make and use the samereference being had to the accompanying drawings in which like referencecharacters refer to like parts throughout.-

The-object of the invention is to provide a refrigerator adapted moreparticularly to be set up permanently into the framework of a houseunder construction although it may be built independently thereof.

I propose to construct the refrigerator in sections that it may be themore easlly packed for shipping to its destination. The sections are soarranged, however, that they may be easily and readily assembled.

The frame work of the refrigerator is constructed of angle iron to whichis riveted or suitably secured sheet metal and the whole is thenpreferably covered with concrete because of its non heat conductiveproperty and hence its usefulness to refrigerate. In order to avoid thecracking of the concrete because of the slamming of doors that areusually hinged at the side and open outward I employ a sliding door togive access to the food compartment of the refrigerator.

Further objects will appear by referring to the drawings in which Figure1 is a perspective view of my improved refrigerator showing one of thesides broken away; Fig. 2 is a front elevation showing the door brokenaway that the interior parts might be seen; 3 1s a plan view of therefrigerator with the top removed; Fig. 4 is a fragmentary view of thedoor to the ice chamber and partsin connection therewith, looking fromthe interior outward; Fig. 5 is a fragmentary view of the door to thefood chamber showing the mechanism for actuating same; Fig. 6 is asection on the line 66 of Fig. 2 and also a plan of the cam oreccentric; Fig. 7 is a fragment of angle iron employed in making theframe of the refrigerator; Fig. 8 is a side elevation of therefrigerator showing the frame work without the addition of the sheetmetal and concrete; Fig. 9 is a modified form of the rear of therefrigerator, showing a door giving access to the food compartment,similar to the door on the front of the device; Fig. 10 is a skeletonview of the frame work before the sheet metal, cross bars and concretehave been added; Fig. 11 is a perspective view of the door of the foodco1npartment, the front casing being removed; Fig. 12 is a plan view ofthe device before the front and rear door casing have been added,showing the sheet metal covering the top and bent to give place for thestay rods that hold the sections together; Fig. 13 is a perspective viewof the ice pan, and Figs. 14 and 15 are details of braces employed onthe device.

Referring more particularly to the drawings the sides 1 and 2 and back 3are constructed separately and are held together in assembled positionby stay rods 4, four in number, headed as at a and running transverse ofthe refrigerator. screw threaded at one end to adapt them to be screwmounted into angle irons 7 of side 2 and also for the screw mounting ofnuts 6. Sides 1 and 2 are of similar construction, embodying an angleiron such as 7 running up the front, across the top and down the rearand strengthened by a plurality of cross bars 8 made of angle iron anddisposed with apex 9 thereof against one surface of angle iron 7 andsecured thereto by rivets 10 or in any suitable manner. Such dispositionof cross bars 8 tends to retain the concrete in position on the framework covered with sheet metal A more effectively. At 11 I employ a pieceof angle iron disposed with one side flush against the inner surface ofiron 7 and having its upper surface or shoulder 12 projecting inwardlyadapted to be engaged by cross bars 13 recessed as at 14 in a manneradapted to permit surface 15 of bars 13 to lie or rest normally uponsurface 12 of bar 11 so that when bar 13 is assembled with both endssimilarly engaging opposite bars such as 11 and 11 it will hold sides 1and 2 outwardly in a rigid manner. Bars 11 and 11 are recessed neartheir front portions as at c in order to provide clearance for icechamber door 20. The back is formed Said rods 4 are a of angle ironswith one flange horizontal for supporting the covering, of concrete orthe like. The irons are formed to be attached to the side pieces andtogether and with the adjacent edges of the sides form the back. Thesame is true as to the front, except in so far as a less number of suchirons may be needed because of the larger openings which are to beprovided for. Straight across the front in a plane with bars 11 and 11 abar g adapted to form the lower casing for ice chamber door 20. Uponbars 13 is disposed pan 16 mounted upon blocks 18 in a manner adapted tocause the water that collects thereon to gravitate toward outlet opening19 disposed preferably at one corner of the refrigerator in order to bein a convenient position provided it is found desirable to gain accessto the refrigerator from both front and rear.

Access is gained to the ice chamber by means of door 20 pivotally swungupon a bar 21 having bearings in angle iron 7 of side 1 and 7 of side 2and said bar is headed as at 22 and secured in position at its remoteend by nut 23. Upon bar 21 is disposed a plurality of bars or supports24: for ice and running thence backward on an incline to and securedupon bar 25 rigidly mounted to angle irons 7 and 7 of sides 1 and 2respectively. Door 20 is provided with a pivotally mounted handle Hcountersunk in the casing of the door and adapted to be a means by whichsaid door may be pulled outward and journaled upon rod or bar 21 untilit comes to rest or abuts against the under sides of bars 24 whereuponsaid door will lie in the same plane with said bars 2 f so that the icemay be placed upon said door 20 and slid into the ice chamber upon bars24 in a most advantageous manner without any racking or breaking of therefrigerator. Furthermore door 20 is constructed of a frame 26 supportedby braces 27 and may have its sides lined with any suitable packingmaterial to cause said door 20 to fit snugly against its adjacent frameor casing, as indicated at h in Fig. 1. Below the ice chamber is thefood chamber divided into any suitable number of compartments and havinga frame covered with sheet metal and concrete for its bottom. The frontof the chamber is closed by a slidingly mounted door 28 adapted to beslid in a manner that will expose one half of the food chamber at atime. The mechanism for thus actuating the door embodies casings 3030rigidly secured to door 28 and adapted to slide upon correspondinglyshaped inner casings 3l-31 rigidly secured to the front portions ofangle irons 7 and 7 of sides 1 and 2 respectively and adapted to form abox covering for weights 32-32 connected one on either side to door 28by ropes 33 riding over pulleys 31-34. journaled on bearings secured tothe upper portions of casings 31-31. The total weight of members is alittle greater than that of door 28 in order that door 28 will tendnormally to rise, said door 28 may be held, however, in any desiredposition within the limits of its movement by turning the handle 35rotatably mounted in cross bars 36-36 of door 28. Said cross bars arecovered on one side with metallic plates 37 adapted to form a bearingfor shaft 38 of handle 35. To the end of shaft 38 is rigidly secured acam or eccentric disk 39 having a bearing or being supported betweenbars 10 and 4:1 mounted in the casing of the food chamber as seen inFig. 2. Bar 4:1 is slightly thicker than bar 40 in order to adapt cam 39when turned in the direction indicated by the arrow to engage in awedging manner bar 41 because of the constant distance between ring 12rigidly held to shaft 38 and cam 39. The turning of handle 35 and theconsequent wedging of cam 39 upon bar 41 further serves the purpose ofdrawing door 28 tightly against its adjacent casing of the refrigeratorand the consequent closing of the door 28 in an air tight manner.

The rear or back part of the refrigerator may be also provided with adoor such as 13 built similar to door 28 and sliding-1y mounted in thesame manner as more fully shown in Fig. 9. Access to both front and rearportions of the refrigerator may be found desirable in the event thatthe refrigerator is placed in the wall of two adjoining rooms of thehouse. In this last described construction, however, the ice chamberwill not be accessible from the rear but the portion corresponding tothe door in front will be provided with a frame 44 shown in Fig. 9 andupon said frame may be mounted a piece of sheet metal A. and concrete asin the case of sides 1 and 2 and back 3 of the former construction.Slots 50 are provided in the rear wall of the ice-pan 16 for rods 24.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is:

1. In a refrigerator formed with an ice chamber. a door to said chamber,the same being pivotally hung on a transversely disposed bar engagingthe door between its upper and its lower edges, a plurality of barsextending from the said first mentioned bar across said chamber, thesaid latter bars engaging one edge of the said door when the same isopened whereby the said door extends outwardly in the form of a shelfand substantially in the same plane with the said latter mentioned barswhere by the said door and the said bars form Eieans for the passing ofice into the cham- 2. In a refrigerator, a door adapted to he slidvertically and having casings secured on its vertical edges andoverlying the same, casings secured to the refrigerator adapted for theengagement of the former casings therewith in the movement of the door,the latter casings being of a form to provide a vertically extendedchamber between the casings, and a counterweight applied to the door forthe movement of the same, the said weight traveling in the said verticalchambers.

3. In a refrigerator, the combination with frames, of two barsvertically disposed in the doorway of the refrigerator and of differentthicknesses from front to back, a vertically sliding door, a lock in thedoor comprising a shaft passed through the door between the said barsand having at its inner end a cam faced disk whereby the turning of theshaft will press the cam-face of the disk against the thicker of thebarsand thereby retain the door in chosen position.

In testimony whereof I have hereunto aflixed my signature in thepresence of two witnesses.
